Quantifying group problem solving with stochastic analysis

- 08 Nov 2010

- pp 40

TL;DR: How group performance is related to several heuristics about group dynamics in performing several typical tasks is discussed and the novel stochastic modeling in learning the structure of group dynamics is given.

Abstract: Quantifying the relationship between group dynamics and group performance is a key issue of increasing group performance. In this paper, we will discuss how group performance is related to several heuristics about group dynamics in performing several typical tasks. We will also give our novel stochastic modeling in learning the structure of group dynamics. Our performance estimators account for between 40 and 60% of the variance across range of group problem solving tasks.

In this paper, the authors will discuss how group performance is related to several heuristics about group dynamics in performing several typical tasks.

Figure 1: Left: The voice segments in our data set normally last 0.05 second and no longer than 0.5 second; They are normally 0.2 seconds apart when appearing in the same clause. Right: Aligning voiced frames could be a robust way to align data collected by different embedded devices deployed in close distance; When aligned, the pitch signals collected by different embedded devices are normally equal to each other.

Table 2: The HMP parameters for the four tasks summarize the different dynamics-performance relationships in both the task dimension and the performance dimension. In this table, covariate f represents performance score, latent state s1 and s2 respectively represent the state of making progress and the state of not making progress, and the observations are change of speaker and duration of clause/silence.

TL;DR: The results show that different performance clusters have different interaction types and the groups with high and low performance have a structure where the group members are influenced by one or more people, in contrast to one-to-one pairwise influences.
